/nyc-hpd

What it does

Provide an address, BBL, or BIN and get the HPD record for a residential building. The skill establishes HPD’s source coverage from publisher documentation rather than inferring an exemption from building class, then queries violations, open violations, complaints, and registration data. Class C (immediately hazardous) violations are flagged prominently, and open violations are grouped by severity class.
